Erratic had this to say on a different thread of this topic:

Previously in the game you had the ability of multiple Res Debuff weilding Defenders and Controllers coming together for far more debuff than Sonic Blast (the topic of this thread) provides when paired with other Sonic Blast users.
Consider 8 Radiation Defenders pre-I5:
AMx8 - Adds +200 to base damage, meaning you only need to 3-slot your damage powers to get the other +100% necessary to be at cap.
EFx8 - Adds another 300% to damage to the capped amount for 700%
That has been doable since launch.
The debuff amount is lower on Sonic Blast and has a short duration, unlike things like EF, Tar Patch, or Freezing Rain.

Erratic makes a great point about the -res and Blue_Volt's number show this set is pretty much in line with the other sets damage wise. I don't think this set is overpowered.
